One-Stop Installation Service: Hydronic Underfloor Heating Piping & Pea-Gravel Concrete Backfilling

This on-site installation service utilizes aging-resistant PEX piping (16mm diameter) known for high-pressure resistance and excellent thermal stability. The process begins with laying aluminum foil reflective insulation rolls, followed by securing the pipes with clips in a smooth, efficient layout. Once the piping is installed, a pea-gravel concrete backfill—using fine-aggregate pea-gravel mortar—is applied to protect the pipes and ensure uniform heat conduction. Expansion joints are incorporated during construction to prevent floor cracking caused by thermal expansion and contraction. Pressure testing is conducted throughout the process to guarantee a leak-free system. The service covers insulation laying, piping layout, backfill pouring, and pressure acceptance testing, making it ideal for heating projects in unfinished properties. The system operates via low-temperature hot water radiant heating, providing a gentle temperature rise and a comfortable, cozy feel—perfect for long-term home heating. Standardized installation ensures the system’s long-term, stable operation.
